One of my test apps have been working up till b14, but saw some failures with b15. These apps all involves concurrency and thread waiting. Any recent changes in GF that might have caused this?

On the client I got these error

Failed to connect to the test webapp.java.net.SocketException: Unexpected end of file from server
